Urinary Frequency

Introduction Urodynamic studies (UDS) generate information about bladder function that, currently, no other testing can provide. Though clearly not necessary to evaluate all lower urinary tract symptoms (LUTS), UDS can be useful when confronted with situations in which the normal noninvasive parameters used to assess LUTS, such as questionnaires, flow rates, and postvoid…

After the decision is made to proceed with urodynamic testing, the next consideration is the type of testing to be conducted. Most current urodynamic machines offer only multiple-channel testing because single-channel testing is prone to considerable artifacts.

In general, because it is difficult to predict for the presence of specific voiding dysfunction in…

Although no clear criteria exist for differentiating neurogenic from idiopathic DO, it has been suggested that unstable bladder contractions occurring as a result of neurological disease may be more likely to result in urge incontinence (17) and have a greater amplitude. Regardless, perhaps the most common urodynamic pattern seen in patients with idiopathic OAB…

Patients with neurogenic OAB tend to have severe symptoms that are more difficult to treat pharmacologically. It is not immediately clear that the overactive contractions experienced by patients with neurological conditions are necessarily of greater amplitude or occur earlier during filling, although there is some indirect evidence to support this contention (13). Phasic detrusor…

Introduction The American Urological Association has published guidelines for the surgical management of female stress urinary incontinence (1). According to these guidelines, the objective demonstration of stress urinary incontinence should be documented prior to initiating surgical therapy. This can be accomplished with physical examination (filling the bladder and observing stress incontinence with cough…

“The overactive bladder syndrome has become an accepted way to simplify a complex array of symptoms and leads people to believe that an overactive bladder is an independent disease in itself. However, the truth is not as simple as this, as there are usually several factors at work explaining the symptoms. This is also…
